This is a lesson about elemental abundance in solar wind. Learners will count elements extracted from a simulated sample and learn how the extraction of atoms from the Genesis samples help scientists have a better understanding of the abundances of...(View More) elements from the solar wind. The hands-on experience helps students to discover that the elemental abundances from the sun can be used as a baseline to compare with the diverse bodies of our solar system.(View Less)

This is a lesson about elemental abundance in solar wind. Learners will simulate the extraction of elements from the Genesis wafers by counting elements extracted from a simulated sample. This will help them learn how the Genesis samples help...(View More) scientists have a better understanding of the abundances of elements from the solar wind - and how they can be used as a baseline to compare with the diverse bodies of our solar system.(View Less)

This is an activity about the use of light to learn about space. Learners will use colored filters to examine slides of stars and nebulae. These filters show how astronomers distinguish stars of different temperatures and nebulae with different...(View More) compositions.(View Less)

This is an activity about the position of the Moon and the Sun in the sky. Learners will use styrofoam balls to model the interactions between the Earth, Sun, and phases of the Moon. This is Activity A-5 of Universe at Your Fingertips 2.0: A...(View More) Collection of Activities and Resources for Teaching Astronomy DVD-ROM, which is available for purchase.(View Less)

This is an activity about measuring craters using shadows and geometry. Learners will make a model crater and use a light source to make a shadow. When they are familiar with the techniques for estimating depths from shadows, they will apply their...(View More) skills to a photograph of three lunar craters. This is Activity C-14 of Universe at Your Fingertips 2.0: A Collection of Activities and Resources for Teaching Astronomy DVD-ROM, which is available for purchase.(View Less)

This is a lesson about measuring star size. Learners will use eclipsing binary systems to measure star diameters. This is Activity G-8 of Universe at Your Fingertips 2.0: A Collection of Activities and Resources for Teaching Astronomy DVD-ROM, which...(View More) is available for purchase.(View Less)

This is a lesson about planet formation. Learners will observe and describe differentiated samples in the Meteorite Sample Disk (or photographs), conduct experiments to model the separation of light and heavy materials within a planetary body,...(View More) relate meteorites to the core, mantle and crust of asteroids, and model the break-up of differentiated planetary bodies to expose the interior layers. Materials lists, and advanced preparation and procedural tips are included. This is lesson 11 of 19 in Exploring Meteorite Mysteries.(View Less)

This is an activity about gravity. Learners will fill out a questionnaire to assess their ideas about how the Earth is shaped and how things fall here and at different places around the planet. Then, in small groups, learners will discuss how...(View More) gravity works as a force and confront previous misconceptions related to gravity and the Earth. This is Actividad 3.1 as part of El Universo a Sus Pies, a Spanish-language curriculum, available for purchase.(View Less)
